Work out the value of angle x and how ??

Mathematics

frutty [35]2 years ago

Answer:

160 degrees

Step-by-step explanation:

Step 1: A straight line is 180 degrees. So 180 - 100, is 80 degrees. as the opposite angle measurement of the 100 degree.

Step 2: An isosceles triangle has two equal angle measurements, so two of its angles are 80 degrees.

Step 3: All angles in a triangle equal 180 degrees. So add them up (we will call the missing angle, Z)     180 = 80+80+Z.      which equals 180= 160+z

Step 4: Solve it. You subtract 160 from both side which comes out to 20 = Z.

Step 5: Now you have the opposite angle of X. Going back to step 1, A straight angle is 180 degrees. 180 - 20 = 160. X = 160 degrees

Genrish500 [490]

Answer:

Step-by-step explanation:

1/4x + 1/2x + 1/4x = 360

4(2/4x + 1/2x = 360)

2x + 2x = 1440

4x = 1440

x = 360

1/4(360)= 90 Clermonth

1/2(360)=  180 Central

1/4(360)= 90 other schools

Javier has a basket of oranges and apples. The number of oranges is 2 more than twice the number of apples in the basket. The di
Soloha48 [4]
O=2a+2,  

o/2-a/2=4  this is your system of equations, 

It you wish to solve for apples, then simply substitute o from the first equation into the second equation...

(2a+2)/2-a/2=4  multiply both sides of the equation by 2

2a+2-a=8  combine like terms on the left side

a+2=8  subtract 2 from both sides 

a=6   

So Javier has 6 apples in the basket.

You toss a coin a randomly selecte a number from 0 to 9. What is the probability of getting tails and selecting a 9?
In-s [12.5K]
First lets find the probability of landing tails. Because there is 1 way to get tails and 2 possible outcomes, the probability is 1/2.

Now, lets find the probability of selecting a 9. Since this includes 0, there are 10 possible outcomes and 1 way to get a 9, so the probability is 1/10.

To find them combined, multiply:

1/2 * 1/10
1/20
0.05

Hope this helps!
